What is your connection rate? It could be that you are forking off a
whole ton of imapds per second and so you have high cpu usage and not
as much I/O usage.
In the next release of the Cyrus 2 imap server, there will be the
feature where imap connections can be reused and so you don't need to
fork a new imapd for each connection.
If you are doing webmail and soley webmail, it may not really make
sense to have an imap server in the loop at all. If you do need an
imap server, maybe you want to look for something that does both http
and imap. I know Mirapoint has a product like this and there should be
others.
On a side note, a smart web client (possibly with some server mods)
can take advantage of the cyrus cache files and get even better
performance.
